Embodiment 1

[0065] The QoS negotiation process in the existing network can be realized by the UE sending a context activation request to the network.

[0066] Figure 4 is the process of PDP context activation in TS 23.060, as shown in Figure 4, the accompanying QoS negotiation process is as follows:

[0067] 1) UE sends a PDP context activation request including QoS requirement information to SGSN. An optional QoS range is given in the QoS requirement information, which can be a continuous QoS range or a series of discrete QoS. The QoS information contains a minimum acceptable QoS and a recommended QoS. QoS information may include information characterizing parameters such as delay, jitter, bit rate, and the like. For example, when multiple media formats with different bit rates are available for the initiated service, a series of optional discrete bit rate values ​​from the lowest to the highest can be given in the QoS requirement information at this time. However, the rate required b...

[0080] The following describes the QoS negotiation process in the evolved network.

[0081] FIG. 5 shows the resource establishment process triggered by the network side to complete the service negotiation through signaling interaction on the established IP bearer in the evolved network. There is no QoS negotiation mechanism in the resource establishment process of the current evolved network. In the present invention, the QoS negotiation mechanism is introduced into the wireless network resource establishment process, which avoids the complexity of the resource establishment process and the high probability of call rejection caused by possible repeated QoS negotiations. risks of. As shown in Figure 5, the bearer establishment process in the evolved network includes the following steps:

[0082] 1) The UE and the opposite end perform signaling interaction through IP bearer to complete the service negotiation. The QoS negotiation result reflects the terminal capability and wil...

Abstract

The invention provides a service quality arranging method that comprises following steps: a. when resource is built, a QoS range for selection is provided in QoS request information sent to network; b. said network selects QoS based on said QoS range; when a series of discrete Qo S values is given in QoS range, the optimized one can be selected. When network changes QoS based on resource and load, referring required QoS range, the complexity of repeated arranging can be avoided, the building time is quickened; the ratio of rejecting of building resource is decreased.

Description

technical field [0001] The present invention relates to wireless communication network technology, in particular, to a method for negotiating quality of service (QoS) in a wireless communication network. Background technique [0002] UMTS (Universal Mobile Telecommunications System) is a third-generation wireless communication network technology standard defined by the 3GPP organization. It consists of a core network, a radio access network and user equipment (UE: User Equipment). The core network includes circuit domains and packet The circuit domain provides services based on circuit switching (such as voice services), and the packet domain provides services based on packet switching (such as Internet access). [0003] Figure 1 is the structure of the UMTS network (the circuit domain part of the core network is omitted), the core network is composed of the service GPRS support node (SGSN), the gateway GPRS support node (GGSN) and the home register (HLR), and the access net...
